Question

Let W= { (x, y, z) |x=1|; y, z ∈ℝ } Prove that W is a subspace of ∈ℝ
How can I resolve this ? .

Answer 1

Answer:

Step-by-step explanation:

Generally

Work = Force * Displacement OR

Work = Surface Tension * Change in Surface Area

But a bubble has two surfaces- the outer and inner Surface, hence

change in Surface Area will be 2 (5 - 2 ) = 2 * 3 cm² = 6 cm²

Work = 0.06 N/m * 6 cm² = 0.06 N/m * 6 (10^-2)² m².

Work = 36 * 10^-6 Joule
